Windows can connect to the network, but does not open the Web page, the DNS of the server cannot be resolved

First of all, I would like to say that as a student who has just finished the computer network class, but also completed the school and Stanford a difficult level of network experiments, I think that the computer network is still reluctant to get started, for all kinds of before just heard a variety of TCP, HTTP, routers, switches, LAN, Wan and so on have a clear understanding of, but, but ... Sure enough, the theory is still to combine actual combat, especially in today's complex multi-terminal network world of practical experience decisive important ah Ah.

Well, forgive me above with the title of BB, because of the computer appeared this problem, to my learning is to think of all kinds of possible and solutions are used, really have the feeling of wits ... Been tortured for a long time, but, but. Finally solved, so in this talk about my solution, in case someone encounters with me the same problem, can not be tortured so much, because most of the online methods are still eggs ah.

My Computer system is win8, the problem arises:

1, plug in the network cable, the Internet center shows Internet access, can through the campus network of Ruijie Login

2, TCP settings automatically get IP address, automatically get DNS server and alternate DNS server address

3, through the query network details, display the IP address, the DNS server address obtains the correct

4, the DNS server is available, confirmed by the roommate's computer

5, using the cheetah free WiFi diverging WiFi, the WiFi can be connected to the network

6, Ping the gateway, pass; Ping DNS server, pass; Direct Ping www.baidu.com, pass

7, the computer steward measured the speed, can be measured

8. Proxy Server Disabled

But

But

1, a variety of browsers do not open

2, QQ login not on

3, the use of other applications on the computer indicates that the network connection failed

、、、、、、

So, there's been a variety of attempts.

1, somehow, the first reaction is to restart the computer, and then the egg

2, the Network Center TCP settings confirmed several times, and then the egg

3, manually set up a DNS server, select a different DNS server to try, and then eggs

4, computer butler, network repair, and then eggs

5. CMD input command: ipconfig/flushdns, and then egg

6, recall the previous update of the computer, uninstalled the latest updates, and then eggs

7. Control variable ~ ~ ~ I can't connect my wifi, but my eggs

8, all kinds of Baidu, try a variety of programs, and then eggs

9, Crazy ... And then the egg

10, finally, finally, found an order (here should have flowers applause):netsh winsock reset

will be the Winsock restore to the default state, and then restart, decisively connected to the net, so the computer appears above the phenomenon of the reason is obvious, the computer system internal directory Winsock is changed, resulting in network configuration error, so even if the computer settings are not wrong, However, when Winsock transmits information to a network connection, the parameter changes, causing the correct response to be received, and the correct request cannot be made.

Before the network programming is not associated with the system, directly is the implementation of the principle, so for the Windows network programming interface has not touched, through this time know that the Windows Network programming interface is Winsock, The reason why this command is useful is that my computer is not connected to the Internet through various analysis tests above, it is unrelated to the network, is not related to the router, has nothing to do with the DNS server, has nothing to do with the various networking settings on the computer, and is not related to the system. However, when this problem occurred I did not install any software, just uninstalled a few, including: Itudou, potato video, Storm audio, Chrome browser ... Which is the change of which I do not want to study, just, sister can Ann you can not unload you!! The Wisp!! Really worthy of the name of rogue software, inexplicably let people waste so much time and energy to find problems, although their own future is to do it this line, but must remember to adhere to the moral bottom line, relying on technology to win applause and not other things
